170-0164 Stealth air cleaner kit. For 58mm S&S throttle body

This S&S Stealth air cleaner kit is engineered specifically for Twin Cam riders running a 58mm S&S throttle body. The kit is designed to be used with your stock air cleaner cover for a sleeper look, or it can be paired with various S&S optional covers. The backplate is constructed from advanced synthetic polymers, similar to those used in high-performance automotive manifolds, providing excellent thermal stability and chemical resistance. This material significantly reduces heat transfer to the intake charge, improving induction efficiency. It is a direct fit for 2003 to 2017 Twin Cam models equipped with the S&S 558678 58mm throttle body.
